feat: Implement recipe selection with backend integration

Backend changes (C#):
- Add SelectRecipe method to MachineBridge for recipe selection
- Add currentRecipeId tracking in MainForm
- Implement SELECT_RECIPE handler in WebSocketServer

Frontend changes (React/TypeScript):
- Add selectRecipe method to communication layer
- Update handleSelectRecipe to call backend and handle response
- Recipe selection updates ModelInfoPanel automatically
- Add error handling and logging for recipe operations

Layout improvements:
- Add Layout component with persistent Header and Footer
- Create separate IOMonitorPage for full-screen I/O monitoring
- Add dynamic IO tab switcher in Header (Inputs/Outputs)
- Ensure consistent UI across all pages
